Emerald Ash Borer

Emerald Ash Borer (EAB)

The emerald ash borer (EAB) is a metallic green wood-boring beetle of about 1 to 1.5 cm in length that attacks all native species of ash trees, typically killing them in two to three years. Its larvae bore tunnels under the bark to feed on inner bark tissue. The tunnels cut the flow of nutrients and water to leaves, causing the tree to die. Native to China, this invasive species was discovered in Windsor Ontario in 2002. Since then, the pest has spread into other areas of Ontario and Quebec and to 15 states in the USA.

TreeAzin is injected into the trunk and quickly spreads into the entire tree vascular system. The emerald ash borer larva ingests the product which stops the larvae from developing and eventually kills it. On top of that, when the female adults eat the leaves of a treated ash they become sterile.
